TL;DR: In this article, it was shown that critical and subcritical N = 2 string theory gives a realization of a superfield extension of the topological conformal algebra, and that the vanishing of the background ghost charge can be explained.

TL;DR: In this article, a general gauge theory in the lagrangian approach is accomplished in closed form, and a new class of diagrams is revealed, required by BRS-symmetry but completely definable only from the requirement of unitarity.

TL;DR: In this article, the spectrum of anomalous dimensions in 2D quantum gravity has been investigated and a formulae for the spectrum has been found for 2D-quantum gravity.
Abstract: We resolve renormalization problems, indicated in Ref. 1 and find explicit formulae for the spectrum of anomalous dimensions in 2d—quantum gravity. Comparison with combinatorial approximation of random surfaces and its numerical analyses shows complete agreement with all known facts.

TL;DR: In this article, the quantization rules for gauge theories with open algebras are generalized to the case of linearly dependent generators and the solution for the general case of such a hierarchy is given.
Abstract: The quantization rules for gauge theories with open algebras are generalized to the case of linearly dependent generators. The given zero-eigenvalue eigenvectors of the generators may also be linearly dependent and possess zero-eigenvalue eigenvectors which may also be linearly dependent and so on. We give the solution for the general case of such a hierarchy.

TL;DR: In this article, it was shown that the two-point function χ(λ,N), in which λ is the cosmological constant and N−1 is the string coupling constant, obeys a scaling law χ (λ, N=N −(m+1 2 ) ⨍((λ c −λ)N m/(m+ 1 2 ) ) in the limit in which n−1 goes to zero and λ goes to a critical value λc; this transition is a "condensation of handles" on the world sheet

TL;DR: In this article, the authors define the continuum limit and compute the partition function for closed surfaces of any genus, and discuss the appropriate way to define continuum string perturbation theory in these systems and show that the coefficients (as well as critical exponents) are universal.
